3 Claims. (Cl. 251-159) This invention relates to iluid pressure valves and more particularly to `a uid pressure regulator.

An object of this invention is to provide an im- ;:proved gas pressure regulator with a more readily replaceable valve element.`

Another object of this invention is to provide f a `gas regulator which may be installed either horizontally or vertically in a gas line and which is provided with means whereby the 4valve disc can be readily removed and replaced without disturbing the valve or any other part of the regulator. Y

In accordance with the 4general features of this invention there is provided a fluid pressure regulator `especially adapted for use in a gas line and which comprises a casing including inlet and outlet passages having valve means associated with `one of the passages to control the'ow oi gas therethrough and which valve includes a detach- `able disc which is laterally removable from the description taken in connection with the accompanying drawing which illustrates a single embodiment thereof, and in which Figure l is a cross-sectional View taken through a gas pressure regulator embodying the features of this invention.

Figure 2 is a fragmentary plan view of an end of the regulator looking through the opening through which the valve disc is adapted to be removed.

Figure 3 is an enlarged fragmentary sectional view similar to a portion of Figure 1 but showing the valve disc in the process of being removed from the valve through the lateral opening provided in accordance with the features of this invention. l p

The reference character I0 designates generally a gas pressure regulator casing comprising a bottom II and a top or cover I2 between which is clamped a weighted diaphragm I3. The parts are secured together by bolts I4 in the usual way. The weighted diaphragm I3 is spring' urged by means of a spring I5, one end of which abuts the weighted diaphragm I3 and the` other `end of which abuts an adjustable screw stud I 6 threaded in an extension Il on the Vcover I2. This adjustable stud or screw I6 has threaded on it a lock` nut I8 normally enclosed in a cap I9 threaded on the extension I1; i i

Also it should be noted that the upper part of the casing Iris provided with a vent opening 20 formed in the cover part I2.

Located in the lower part II in the casing I0 is a series of levers including a lever 2l and a bell 10 crank lever 22. The lever 2I` is pivoted at 23 to the casing part I I and has Vone end pivotally connected at 24 to a boss 25 secured to the underside of the weighted diaphragm I3.

Aliivotally connected to the lever 2I between its l5" ends is an intermediate link 26, one end of which is pivoted to lever'2I and the other end of which is pivoted to a fre'eend of bell crank lever 22. Bell crank lever 22 is also pivotally carriedat 2l on the casing II`. A`

The other end, of thelbell crank lever 22 is pivotally connected `at 23 to a reciprocatory valve member 30 whichis adapted to be oscillated into and out of closed position in a passage 3|.

The passage 3l is disposed in communication 25 with an inlet passage 32 which is threaded to receive one end of a pipe. Diametrically opposite the inlet passage 32 is an outlet passage 33 formed in the casing part I I and which is also adapted to receive an end of a gas pipe, It should be noted 30 at this time that the construction of the gas regulator illustrated in the accompanying drawing is such that the regulator may be mounted with equal advantage in either a horizontal or a vertical position in a gas pipe line. 35

The inlet passage 32 is formed in a nipple 34 threaded at 35 into one end of the casing part I I. The threaded nipple 34 has a reduced passage 36 adapted to establish communication between passages 3I and 32. This reduced passage 36 ter- 40 l minates at 3'! in a valve seat cooperable with a valve element or head 38 detachably carried in a free end of the valve 30.

At this time it should be noted that my invention is concerned with the valve element 38 and 45 not per se with any other structure of the gas regulator previously described. As a matter of fact, any usual or suitable gas regulator mechanism may be employed for operating the valve 30, and this valve 3D may be of any conventional or desired shape as long as it embodies the features of the invention which I will now proceed to describe in detail. 1

The valve element 38 is dovetailed in a slot 39 formed in an end of the valve 30 as 55 best shown in Figures 2 and 3. This valve element 33 may be made of any suitable mate' rial such, for exampleyas ber, and is carried in a channeled frame 4! which has formed integral with it laterally ofiset'handle means 4l. This handle means 4l may be apertured at 42 to receive the end of a wire or other hook for raising or lowering the valve element 38 or, in other words, for oscillating the valve element in the end of the valve 30. The channeled metal element 40 is of a V-shaped cross-H section so that the fiber valve element 30 is disposed inside the same and is movable therewith.

eected by removing the plug 4S and by then pulling the valve element 38 out of the dovetailed slot 39. inserted by simply pushing it downwardly in the dovetail slot 39. It will of course be appreciated that the inward movement of the element 38 will be limited by the oiset handle means 4l which `will come into Contact with the top side of vthe valve'S as is evident from Figure 1.

This replacement of the valve does not in any way necessitate any disturbance of any of the other parts of the regulator, nor does it require that the regulator be in any way disconnected from'theY pipe line. All that is necessary to be done in addition to what has been described hereinbefore'is to turn off the gas prior to the removal of the plug 46. Y I

Now- I desire it understood that although I have illustrated and described in detail the preferred embodiment of this invention, the inventionfis not' to be thuslimited, but only so far as Y Thereafter a new valve element may be defined by the scope and spirit of the appended claims.

I claim as my invention:

l. In a uid pressure regulator valve, a removable valve Vhead slidably dovetailed in the 5 Vvalve and including offset handle means project- 4a slot therein in the Agate end thereof, a gate member slidabl'y insertable in said slot, an offset apertured handle on said gate member projecting freely beyond said valve, the offset in said 20 handle serving as a stop to limit the inward movement of said member, said casing having an f opening therein adjacent said member, and a removable closure associated with said Opening, whereby when said closure is removed a suitable 25 instrument may be inserted through said opening and engaged in the aperture in said handle for the removal and replacement of said gate member alone.

3. A valve construction, including a valve seat, a valve member movable relatively to said seat, said valve member having a dovetail slot therein in alignment with said seat, and a removable valve head shaped for insertion in said dovetail slot, said valve head carrying ra handle projecting beyond said valve member and having an offset therein to limit the insertion of said head in said slot, whereby said head may be removed and replaced and when inserted in said valve member becomes automatically aligned 40 with said valve seat.
